Why is cotton used in paper?
Cotton is one of the strongest and most durable fibers known to man. Papers manufactured from cotton fiber will last longer and hold up better under repeated handling and various environmental conditions than paper made from wood pulp. Generally, given reasonable care, a customer can expect one year of usable life for every 1% of cotton contained in the sheet. Typically cotton fiber papers are made of either all cotton fiber (100% cotton) or a blend of cotton and wood pulp. The most common blend is made of 25% cotton and 75% wood pulp. Other blends include 50% and 75% cotton fiber, the balance of each being made up from wood pulp.
